Description

Technical Field

[0001] The utility model relates to the technical field of bottle mold shaping, in particular to a PET bottle mold shaping device. Background Art

[0002] PET bottle refers to a bottle that contains a plastic material called polyethylene terephthalate, or PET for short. It is a polymer produced by the combination of terephthalic acid and ethylene glycol. After the PET bottle mold is demolded, the mold base needs to be shaped to remove the burrs on the outer surface of the mold base, so as to improve the quality of the product.

[0003] Patent authorization announcement number CN 214393619 U discloses a PET bottle mold shaping mechanism, including a base, both sides of the upper surface of the base are fixedly connected to support plates, the tops of the two support plates are fixedly connected to top plates, the lower surface of the base is fixedly connected to a first motor, the output shaft of the first motor is fixedly connected to a connecting shaft, the end of the connecting shaft away from the first motor is fixedly connected to a workbench, and four side plates are fixedly connected to the four corners of the upper surface of the workbench. The PET bottle mold shaping mechanism is provided with a first motor, a connecting shaft, a workbench, a side plate, an electric push rod and an arc-shaped limit plate. When the device is in use, the electric push rod can be moved laterally until the four arc-shaped limit plates fix the PET bottle mold, and the mutual attraction between the first magnet and the second magnet can increase the stability of the arc-shaped limit plate, which solves the problem that the existing device has a relatively single fixing method and poor fixing effect when in use.

[0004] However, the above technical solution has the following shortcomings: the bottle mold is limited by pushing the limit plate through four groups of electric push rods, and the electric push rods are located on a rotating workbench, which causes the wiring harness that provides power and control signals to the electric push rods to easily become entangled, resulting in high production and maintenance costs of the equipment and poor overall practicality.
